[DL] *Extended Deadline* CfP: Workshop on “Explainable Logic-Based Knowledge Representation” (XLoKR 2020) in conjunction with KR 2020

[Francesco Kriegel]

CALL FOR PAPERS

Workshop on “Explainable Logic-Based Knowledge Representation” (XLoKR 2020)
in conjunction with KR 2020

Organisers:
- Franz Baader
- Gerhard Brewka
- Jörg Hoffmann
- Thomas Lukasiewicz
- Torsten Schaub

To make the behavior of knowledge-based systems comprehensible, they need to be able to explain their decisions. In principle, decisions based on logical reasoning are easy to explain since one can use a formal proof in an appropriate calculus to explain a positive reasoning result, and a counter-model to explain a negative one. In practice, however, things are not so easy since proofs and counter-models may be very large, and thus it may be hard to comprehend why they demonstrate a  certain result. In automated deduction, the problem of explaining why a consequence does or does not follow from a given set of axioms has been considered for a long time. In knowledge representation and reasoning, efforts in this direction are more recent, and were usually restricted to certain sub-areas of KR.

The purpose of this workshop is to bring together researchers from different sub-areas of KR and automated deduction that are working on explainability in their respective fields, with the goal of exchanging experiences and approaches. A non-exhaustive list of areas to be covered by the workshop are the following:
- AI planning
- Answer set programming
- Argumentation frameworks
- Automated reasoning
- Description logics
- Non-monotonic reasoning

Important dates:
Paper submission: 0̶8̶ ̶J̶u̶n̶e̶ ̶2̶0̶2̶0̶ 22 June 2020
Paper notification: 1̶3̶ ̶J̶u̶l̶y̶ ̶2̶0̶2̶0̶ new date to be announced
Workshop dates: 12-14 September 2020 (one day, exact date to be announced)

Researchers interested in participating in the workshop should submit extended abstracts of 2-5 pages on topics related to explanation in logic-based KR. The workshop will have informal proceedings, and thus, in addition to new work, also papers covering results that have recently been published or will be published at other venues are welcome.
